▎ 摘　　要

NOVELTY - Method of forming graphene oxide based layer involves preparing solution of graphene oxide, preparing a solution of nanostructures, and applying the solution of graphene oxide and solution of nanostructures onto a surface of substrate (110) to form a graphene oxide based layer with nanostructures. USE - Method of forming graphene oxide based layer used for manufacturing article (claimed) e.g. anode modifier for polymer solar cell. ADVANTAGE - The method provides graphene oxide based layer having sufficiently improved conductive. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of article. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a photovoltaic device. Solar cell (100) Substrate (110) Nanostructure composite layer (120) Active layer (130) Cathode (140)
